so is the boxed frame contributing to the DW in the 17s?

I cannot imagine a boxed frame would contribute to Death Wobble. In theory at least, the extra rigidity of the frame should have the opposite effect. DW is primarily a caster issue that allows the front wheels to start oscillating out of sync with each other because the ends of the axles are moving front to back at different rates. The older SD's with the solid axles and leaf springs don't have the problem because the ends of the axle can't move longitudinally. That movement is what takes the 'whump' out of the bumps, and so improves that aspect of the ride. Lateral movement in the front suspension is also a result of the coil spring design and can cause the front of the truck to seem like its moving side to side in blustery crosswinds (which is the reason I am still driving my '01, I couldn't get used to that feeling, although I did not experienced any control issues with it.

 

Indeed, the boxed frame should improve everything. Except access inside the frame rails for aftermarket accessory addition.

 

That and the problem of water, salt and mud/dust accumulating inside the frame causing it to corrode from the inside out. Open frame rails allow debris to fall out or be rinsed away and dry out.

 

Do we know what alloy Ford used for the boxed frames? I'd hope that it at least has some nickel and chromium in it to reduce corrosion. I'll check...

All Infogalactic says is "the frame is made from 95% high strength steel"

man what is up with the DW threads over there....(17+ super duty section)

 

I worked in our bodyshop the last 10 years before retirement doing the mechanical. We were a BMW Dealer and did a lot of aluminum frame rail and body repairs on Beamers,MB'S Audi's etc You can't rework aluminum fenders, hoods,etc like you can steel so they generally need replacement. Once the car insurers see the escalating repairs due to the aluminum components in the new trucks I expect to see insurance rates to increase to compensate for that. While being much lighter helping with mpg aluminum body vehicles are very expensive to repair but are the future along with carbon fiber.

 

You would be hard pressed to find a body shop around here where any of them even know how to work on body panels. I know 3 guys that run body shops and they all say that it is faster and cheaper to just swap parts out instead of fixing them and all they hire anymore are parts swappers instead of of people with actual body work skills.

 

Which trucks have aluminum cabs? I know the hoods on Peterbilts are aluminum but thought the cabs were steel.

 

 

The point of starting this thread had NOTHING to do with Aluminium!
It had everything to do with Ford, and in my opinion the lack of quality of certain components.
